I feel that those post neglects the potential for traditions to be revived. Maybe the revival will be different from the original, but it very well may constitute an improvement as they can learn from subsequent reactions to the movement. Traditions also have a tendency to get locked into certain flaws and those who revive it have an opportunity to avoid at least the most obvious of those.
One interesting example of traditions being revived might be the Historical European Martial Arts community: there is no unbroken lineage of teachers who would have kept the art of fighting with, say, 15th century weapons alive to this day. However, there are surviving manuals that were written by masters of that time, and communities have sprung up which have taken the manuals, started training according to them, and turned the whole thing back into an actual living martial art where people are once again figuring out the best ways to fight using these weapons.
